The 2012 NFL scouting combine is in the books, and prospects are left with only their pro days. Pro days aren't as important as the combine is, but they can be key in determining a player's stock.
If a player already dominated at the combine, he probably doesn't need to do much at his pro day. He's already proven himself, so what more does he have to show?
It's the guys who disappointed or did not perform at the combine who have something to prove. These guys need big performances to maintain or elevate their stocks.
